Step 9. Mount the precipitate on a holder such as a ring and disk, and cover with Mylar film. Label the sample according to counting room protocol. 

An an alternative to printing the bottles or to affixing labels subsequently it is possible to apply the label at the moulding stage. Paper or thermoplastic film labels are printed in advance and are placed in the moulds before parisons are collected, being held in position by vacuum adhesion of the label takes place when the blown material fills the mould.

Remove one glass plate from the gel and cover the exposed surface with cellophane film. Label with radioactive ink (preferably 35S) and autoradiograph for 1-2 days at -20°C (Appendix IV and Section 3.1.2.). Alternatively the gel may be fixed by immersion in 10% acetic acid for 15-20 min, washed 1-2 min in distilled water, blotted dry with absorbent paper, covered with cellophane and autoradiographed at room temperature. 

Pressure-sensitive adhesives are used for labelling applications. They are permanently tacky and adhere to the surface of the desired substrate under pressure. A paper or plastic film label is coated with a pressure-sensitive adhesive and applied to a backing layer - usually siliconised paper from which the label can be removed easily. The labels are then printed and sent...

The possibility of thin-film labeling by inert gases during physical deposition (PVD) or chemical vapor deposition (CVD) on a substrate can be applied for diagnostics of the thin layers, during their processing, thermal treatment and durability testing.

Additional precautions must be taken when laminating label materials to metal or other surfaces that can be contaminated by heavy debris or hydrocarbon residues. If grease, oils, or wax-based substances are present at the surface, solvents such as denatured alcohol, heptanes, xylene, or ethyl acetate can be effective as a first phase for preparing surfaces resistant to solvents. The final phase is recommended to be a final wipe with isopropyl alcohol until the surface is dry. Temperature is also an adhesion determinant. Stainless steel surfaces, for example, will maintain low surface temperatures for a longer period of time compared to other substrates. Preheating the surface of these metals with flame burner treatment prior to film label lamination will improve adhesive wet-out to metal surfaces. It is advisable that hydrocarbon oils be removed from these surfaces prior to initiating label contact. 

Labels used for blow molding are typically constructed of paper or polymer film and require a heat-activated adhesive for adhesion purposes. The adhesive can be applied either during co-extrusion when the film is being produced, or at final conversion of the label. During the latter, the adhesive is applied to the reverse side of the label facestock and activated by heat while the label is in the mold. The use of corona discharge treatment on polymer film labels is advised and usually sufficient at a minimum level of 38-40 dynes/cm. Bonding takes place when the adhesive is activated by heat and expansion within the mold. 

Labels used with injection molding processes do not require an adhesive because fusion of the plastic film labels takes place with the injected plastic during molding. Here, film compatibility with the injection molded plastic part is most critical for final adhesion.
